Tha Nang Bridge spans the Kuang River near Pratu Tha Nang (one of the ancient city gates of Hariphunchai), connecting the inner city to the Wiang Yong sub-district. Historically, this area served as a royal pier used by Queen Chamadevi, featuring a small wooden bridge for local transport and river trade. Today, the bridge is more than just a roadway; it is a popular photography landmark and houses the Water Level Station (P.5), which is crucial for monitoring flood risks in Lamphun. The surrounding area has evolved into a vibrant community with riverside cafes and scenic rest spots.
